bear -- make produces an empty compile_commands.json

A simple HelloWorld program bear -- make is no problem, but for the same step of git clone git://g.csail.mit.edu/xv6-labs-2022 this project compile_commands.json is empty

I referred to the related example bear make : empty output json #200 which does not work for me.

Thank you for taking time out of your busy schedule to answer

My mistake, the --verbose output I gave was wrong. I used make clean, and then executed bear -- make, which still didn't work. And I checked that the CC variable in the Makefile was a compiler command, and it still didn't work. . However, the same steps can produce results on the virtual machine Linux, but not on the Mac. this is new verbose： [10:02:58.803263, br, 38545] bear: 3.1.3 [10:02:58.804296, br, 38545] arguments: ["bear", "--verbose", "--", "make"] [10:02:58.804349, br, 38545] environment: [] [10:02:58.804453, br, 38545] sysname: Darwin [10:02:58.804455, br, 38545] release: 22.3.0 [10:02:58.804488, br, 38545] version: Darwin Kernel Version 22.3.0: Mon Jan 30 20:39:46 PST 2023; root:xnu-8792.81.3~2/RELEASE_ARM64_T6020 [10:02:58.804490, br, 38545] machine: x86_64 [10:02:58.804509, br, 38545] arguments parsed: {program: bear, arguments: [{--: [make]}, {--bear-path: [/usr/local/bin/bear]}, {--library: [/usr/local/lib/bear/libexec.dylib]}, {--output: [compile_commands.json]}, {--verbose: []}, {--wrapper: [/usr/local/lib/bear/wrapper]}, {--wrapper-dir: [/usr/local/lib/bear/wrapper.d]}]} [10:02:58.809586, br, 38545] Process spawned.

I noticed that In case：if you are using non default compilers, you might want to write a configuration file to hint Bear which compilers to recognize. Can you give an example configuration file to prompt Bear which compilers to recognize?
Can you give me some more tips?

bear -- make produces an empty compile_commands.json #551
